PROBLEM TO BE SOLVED: To improve durability while performing manual feed threshing work favorably.SOLUTION: A combine includes: a restriction member 29 switchable between a restriction release state opening a grain culm inlet part 10A of a threshing feed chain 10 and a restriction state closing the grain culm inlet 10A a non-contact type detection sensor 31 capable of detecting presence of a detected part 30 when the restriction member 29 is in the restriction release state and a threshing control unit controlling driving speed of a threshing device into an operation state for reaping work when the presence of the detected part 30 is not detected and into an operation state for manual feed threshing when the presence of the detected part 30 is detected. The detection sensor 31 and the restriction member 29 are supported by a frame body 32 supporting a grain culm conveyance device 11.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】枕扱ぎ作業を良好に行うことが可能なものでありながら、耐久性の向上を図る。【解決手段】機体前部側の横軸芯周りでの回動に伴って、脱穀フィードチェーン10の穀稈入口部10Aを開放する規制解除状態と、穀稈入口部10Aを塞ぐ規制状態とに切り換え自在な規制部材29と、規制部材29が規制解除状態であるときに被検出部30の存在を検出可能な非接触式の検出センサ31と、被検出部30の存在が検出されなければ刈取作業用の運転状態になり、被検出部30の存在が検出されると枕扱ぎ用の運転状態になるように、脱穀装置の駆動速度を制御する脱穀制御部とを備え、検出センサ31及び規制部材29が、穀稈搬送装置11を支持するフレーム体32に支持されている。【選択図】図3
